General description
我们的氧化钛（IV）纳米粉末是由二氧化钛纳米颗粒组成的白色细粉末，平均粒径为21nm，表面积为35-65m2/g。TiO2 具有两种物理化学性质不同的主要多晶型物，即锐钛矿和金红石。锐钛矿的光催化活性比金红石更强，但热力学稳定性较低。
We are committed to bringing you Greener Alternative Products that adhere to one of the four categories of Greener Alternatives. This is an enabling product that enhances the performance of perovskite fuel cells, facilitating high solar energy conversion and contributing to more efficient energy solutions.
